MACHINE FOR SPINNING PAPER THREADS.

Application filed July 19, 1909. Serial No. 508,378.

Specification of Letters Patent.

Patented Nov..1,* 1910.

To all whom it may concern:

Be it known that I, ANTON F ject of the German Emperor, residing atWestig, Prussia, Germany, have invented certain new and usefulImprovements in Machines for Spinning Paper Threads, of which thefollowing is a specification.

The spinning of thread from paper strips is well known. However, it hasbeen hitherto very diflicult to form a thread that is uniform, round anddurable.

The object of my invention is to provide a spinning machine whereby athread will be produced that will have the above named qualifications.

To illustrate my invention, reference is had to the accompanying drawingin which similar reference letters denote corresponding parts and inwhich- Figure 1 is an elevation and Fig. view of the spinning machine.

Upon the spindle a of the machine a dish shaped drum 1) is borne whichis adapted to receive the paper roll 0 and which has a centrallyapertured cover (Z. The strip of paper-e from which the thread is to bespun, is drawn from the center of the paper roll 0 upward through theopening of the cover and carried to the spool, so that while the drumrevolves the strip is twisted around itself and formed into a thread. Inorder to prevent a non-uniform, slack twisting thereof and also toprevent the formation of knots. I provide a device, which consists of ahollow body f, which is secured to the 2 a plan cover cl and projectscentrally upward above the opening thereof. This hollow body open on thetop and bottom and its upper opening is narrower than that in the.bottom. Owing to this, the strip in passing through and outward from theguide f is first folded or crinkled in longitudinal direction. Thisconstitutes the preliminary rounding of the strip. However. this guidepiece alone would not be sufficient, for the twisting of the strip wouldbegin inside the hollow body or gnide,-preventing the crinkling orfolding of the strip. Therefore, in addition to the body 7", I provideanother device. which consists of a body 9, in form of a grate, buckleor the like, which is mounted in a frame or standards rigidly secured tothe cover (I and which is adapted to occupy a position above the hollowbody UNKE, a subf. This grate is capable 'of'fiItingin this frame orstandards around itshorizontal axisand may be adjusted in the dilferentpositions in any suitable manner, asjfor instance", by the tightening ofa nut g, or the like. The crinkled or folded strip, upon passing outfrom the body f is carried through the said grate so that it alternatelypasses on one and the other side-of the crossbars constituting the grateor buckle and thence to the spool (not shown). This buckle or grateshaped-body g has for its object to diverge the normal direction of thestrip, whereby the twisting of the strip will be caused to take placeonly above the grate or buckle shaped body, permitting the portion ofthe strip below to receive the. prerequisite crinkling or folding. Thetension during the hvisting of the thread is how ever as much importantas the preliminary rounding thereof effected by the crinkling orfolding. This tension is effected at the same time by the grate g. Btilting the latter more or less upon its axis the thread is more or lesstightened or stretched, so that the tightness of the thread can beeasily controlled. The driving of the spindle and the drawing oif of thecompleted thread may be the effect by ordinary means.

IVhat I claim and desire to secure by Letters Patent is:

1. In a machine for spinning paper thread, the combination with aspindle provided with a dish-shaped receptacle which carries the paperroll, of a hollow body open at "both ends, upwardly narrowed, which isrigidly connected with the said receptacle and adapted to crinkle orfold longitudinally the paper strip. and an adjustable body supportedupon and connected with the said receptacle and adapted to engage thestrip above the said hollow body, so as to diverge the strip from itsnormal direction and thereby cause the twisting thereof after it hasbeen crinkled or folded.

2. In a machine for spinning paper thread, the combination with aspindle provided with a dish-shaped receptacle which carries thepaperroll, of a hollow body open at both ends and upwardly narrowedwhich is rigidly connected with the said receptacle and adapted tocrinkle or fold longitudinally the paper strip, and a grate shapedadjustable body connected with the spindle r In testimony whereof Iaffix my sign-Lttnre 1n presence of two wflnesses.

ANTON FUNKE.

and adapted to engage the strip above the X said hollow body, so as todiverge the strip from its normal direction and thereby cause thetwisting thereof after it has been crinkled or folded and according tothe adjusti ment of Which the strip or thread can be 1 more or lessstretched. 1
